Find the Powerful Move #20

For this, the last in this series for now, I reached way back in time and pulled out one of my most favorite games. It's probably not objectively the strongest move, but it remains extremely powerful. Any 14 year old would be proud to defeat his first master in such a way!

I hope you liked this series! I may restart it again in the future once I've played in a few more tournaments. Take care for now!
